In my last post, I talked all about the versatility of the GH4, and how it can bring some pro features to a semi-pro audience — as well as some pro features to some budget-conscious professionals! In this piece, I’ll be talking a little bit more about some of the higher-end applications of the GH4, as well as its partner in crime – the YAGH interface. (Catchy name, right?) The YAGH interface unit, or “the bottom thing” as most folks around here are calling it, adds some really fantastic usability to the system. Firstly, it provides HD-SDI connectivity. To my knowledge, there is no other DSLR on the market that currently sports HD-SDI, unless you get into Blackmagic Cinema Camera territory (Yes, I realize the GH4 isn’t technically a DSLR, nor are the BMCCs – but work with me here). This is a big deal. Not only do we get HD-SDI, but we are given 4 HD-SDI ports. The photo above shows how when paired with something like an AJA Ki Pro Quad, we can record 10bit 422 HQ Prores 4K footage. That’s some serious codec right there. The quad also mounts nicely to the rear on rods, allowing for easy powering with an Anton Bauer d-tap. Add a top handle, and I could see someone shooting with this for very long periods for indie cinema, documentary, or commercial applications. In addition to HD-SDI, we are also given 2 XLR inputs and a full-sized HDMI output – still capable of outputting 4K 10bit. With the added XLR, HD-DI, and 4pin DC power – this is all of a sudden a real, professional camera. There are, however, some drawbacks to this unit. First and foremost, most people will be surprised to find out that once the YAGH unit is installed, all your power must come from an external source. For the setup, I like to hang a Wooden Camera Anton Bauer gold mount rod unit to the rear, pulling off the d-tap and into the 4pin XLR. This isn’t that bad, but it’s to be noted. All those nice new Panasonic badged batteries you got for the camera? Yeah, those aren’t gonna work with the YAGH. The only other real problem I’ve found with the YAGH unit is simply misinformation. One DOES NOT NEED the YAGH unit to output 4K via HDMI into something like an Atomos Shogun. What the YAGH does give you is a full-sized HDMI, proper HD-SDI connections, XLR, audio levels on nice easy-to-see LEDS, and a way to power the camera with a big Anton Bauer battery. Professional users will see these things not as detriments, but as huge improvements. Users who require a slimmer profile, and easier rig, will find themselves opting out of the YAGH unit. Each situation will require some foresight into exactly what you will need – but Panasonic has given us the choice, and that’s saying a lot more than any other camera in this market. Now, with all that being said – this brings me to the next situation people are speaking at length about: External recording with the GH4. While the option to output such high spec codecs is phenomenal, one must again consider their application in what you’re really shooting. In my personal tests, I’ve found the native 4K 100Mbps internal recording to be nothing short of amazing. It hits that beautiful sweet spot between compression and high bit rates — it gives just enough to allow for some flexibility in color grades, but compresses enough to give you 40 minutes of 4K video per 32GB card. I was getting around half an hour per 64GB card recording prores on my Blackmagic Pocket Cam. There’s really something to be said about smart compression. There has always been the cry for uncompressed, but not nearly a loud enough cry for BETTER compression. This video, shot by vimeo user Emeric, displays just how pretty this camera can be! He lists the lenses as very common Panasonic and Olympus glass, recorded internally and graded in film convert. Take a look and see if you’d be kicking yourself for not recording to a Shogun! (I wouldn’t.) Lastly, I want to quickly touch on one more aspect of the camera that I believe needs to be spoken about a bit more. The versatility of the MFT mount. The small flange distance allows us to adapt this mount to most anything — though an optimal Canon EF adapter is still slightly difficult. With the introduction of speed boosters, we are seeing some really amazing things happen. Nikon mount Zeiss glass being adapted and reduced, gaining a stop with no optical quality loss. It’s very exciting! Our GH4 has gone out the door a handful of times loaded up with Zeiss Superspeeds and even some Cooke Glass. I feel that in a rental situation, this camera is allowing people the budgetary option of scaling back the camera body, perhaps down from a 1DC or c300, and scaling up that savings into some absolutely exceptional glass. Here’s a photo of the GH4 fitted with the new Leica Summicron-C 35mm. These lenses are smaller than Cookes, and fit very nicely onto the Hotrod MFT to PL adapter. The instance of lower-cost cameras introducing professional codec options and video features, like peaking, zebra, HD-SDI, xlr, etc., are allowing low-budget shooters to experiment with something that will surely improve your image — the glass in front of the sensor. It is in this that I find the GH4 to be a big deal, giving you options for a high-end studio shoot with an Optimo zoom, feeding a director’s monitor; or in your backpack with a pancake lens, for quick shooting while on vacation. The GH4, as well as the YAGH unit, Hotrod PL adapter, and a whole host of lenses are all here at Rule Boston Camera for rental – and we also offer the GH4 and YAGH for purchase, if you’re so inclined.

In July, Nick Giannino from our sales dept and myself were kindly invited down to Canon HQ in Long Island for an educational seminar. The aim was to talk about Canon’s new line of Cine primes and zooms. About half the seminar was conducted by Mitch Gross, formerly of Abel in New York. He asked what makes a great cinema lens as opposed to a great still lens? Good question – how about long focus pull range; large, glow-in-the-dark focus markings; 11 iris blades to produce subtle bokeh; warm skin tone glass; and ability to handle flares. All these factors have been built into both the Cine EF-mount primes and the PL-mount zooms. Nick and Andrew at Camp Canon The second half of the seminar was conducted by Suny Behar. He conducts a week-long camera test every year for HBO. What camera test, you ask? Well, HBO is the only network that does this: they spend a week with six different cameras, from a Black Magic 4K to a Phantom Flex 4K, shooting footage under a variety of different lighting situations. This footage is then shown to HBO show runners and DPs who are in the process of making camera decisions for upcoming shows. This year all the lenses used on all these camera tests were from the EF and PL-mount Canon Cine line. The lenses were chosen over Cookes, Optimos, Zeiss, etc. HBO was very impressed. In fact, so impressed was David Franco, a DP on Game Of Thrones, he went out and bought the entire Canon Cine line. I heard he paid with golden blood-soaked coins. Lastly, Canon also showed off the new Cine 17-120mm ENG-style large-sensor zoom lens which will be shipping in September. The lens is designed to be a Cabrio-killer with a larger zoom range, better ergonomics and a price point $15K cheaper than the Fuji Cabrio 19-90mm. Lots of low-interest rate options are available for the C300, C500 and lens packages so ask Sales for details. We also have most of the Canon Cine line available in rentals so please call us for availability and pricing. Thanks for reading! – Andrew Barlow, Rental Coordinator, barlow@rule.com
